Trichloroethylene

Basically the pseudo-chloroform. It weighs almost same as chloroform, smells almost exactly like chloroform (but milder) and looks exactly chloroform. Like chloroform, trichloroethylene was also used as an anaesthetic. It is believed to be "less toxic" than chloroform while being a certified carcinogen and degreasing nerves in the face. Trichloroethylene is a professional water and soil pollutant, despite being volatile.
